Title: Improvements relating to arrangements for measuring pressure variations in liquids or gases
IPC: G01L9/00
Filed: 1954-01-08
Abstract: 751,362. Electric indicating systems. DAIMLER-BENZ AKT.-GES. Jan. 8, 1954 [Jan. 9, 1953], No. 629/54. Class 40(1) Pressure variations in a fluid are applied to a diaphragm 3 carrying a stem shaped core consisting of two outer portions 7a of magnetizable material and a central portion 7 of non-magnetizable material, which at some predetermined pressure penetrates equally into two coils 8a, 8b connected in a measuring bridge in which condition the bridge is balanced. Variations in the fluid pressure result in a corresponding output from the bridge which is amplified at V and fed through a phase-sensitive rectifier G and band-pass filter S to an oscilloscope A or a recorder. The diaphragm 3 is clamped between the member 1 and a threaded sleeve 2 or it may be integral with the sleeve. A screwin plug 9 supports the coils 8a, 8b and has a bore 11 through which a damping medium or counteracting pressure fluid may be fed to the top side of the diaphragm. Differential pressures may be measured. For measuring the pressure fluctuations in e.g. the injection pipes of I.C. engines, the chamber beneath the diaphragm is constructed as a portion of the pipe Fig. 2 (not shown). Where hot liquids or gases are being investigated, two diaphragms 3, 3b, Fig. 3, are used, both connected to the core 7, 7a. The hot fluid under test is applied to the lower side of the diaphragm 3b while cooling fluid, e.g. water is fed by pipes 20, 21 to the space between the diaphragms. Tightening rings 16, 17 are provided to pre-stress the diaphragms so as to raise their natural frequencies above the operating range.

Title: Improvements in or relating to railway signalling systems
Inventor: GORE GERHARD WERNER
IPC: B61L1/18
Filed: 1963-01-11
Abstract: 1,020,039. Track circuits. MULLARD Ltd. Jan. 8, 1964 [Jan. 11, 1963], No. 893/64. Heading B7N. A system for detecting the presence of a train on a section of continuous track comprises a signal generator A connected across one end of the track section for producing a plurality of signals of different frequencies, a second generator B connected across the outer end of the section and producing the same plurality of signals at the same frequencies and detectors D1-D3 connected across the track intermediate the generators, each responsive to one generated frequency. The zones over which the generators influence the detectors overlap so that a shunt, i.e. a train axle, across the rails anywhere in section αA prevents detector D1 responding to a signal from generator A and a shunt in section #B prevents it from responding to a signal from generator B. Similarly a shunt in sections #A or #B prevents detector D2 responding to signals from generators A and B respectively and a shunt in sections γA or #B prevents detector D3 responding to the signals from A and B respectively. The arrangement thus provides five subsections, i.e. L-R, R-Q, Q-U, V-T and T-Y which are signalled as occupied when detectors D1, D1 and D2, D2, D2 and D3, D3 are de-energized respectively.

Title: Insulated gate field effect transistor
Inventor: AOKI KENJI
IPC: H01L29/78
Filed: 1987-01-05
Abstract: PURPOSE:To enable a high-speed operation, by providing a surface of a semiconductor substrate with an epitaxial growth layer whose impurity concentration is smaller than that of the substrate and whose thickness is equivalent or below to a width of a depletion layer in a channel region. CONSTITUTION:An epitaxial growth thin film layer whose impurity concentration is smaller than that of a substrate 1 is formed in a channel region 2. For example, the impurity concentration of the substrate is 1X10<17>cm<-3>, and the impurity concentration of the epitaxial growth layer is 1X10<14>cm<-3>, and a length of a gate is 1mum. In this case, a width of a depletion layer extending in the channel region is considered to be about 500Angstrom . When the epitaxial growth layer, whose thickness is equivalent or below to the width of the depletion layer in the channel region, is formed in this way in the channel region on the substrate of high concentration, then this obtained MOSFET is remarkably effectual for suppression of a short channel effect and for improvement of mobility. Further, when the concentration of the epitaxial growth layer is constant, a threshold voltage can be controlled by changing the film thickness of the epitaxial growth layer.

IPC: H03H11/08
Filed: 1991-01-08
Abstract: PURPOSE:To compensate independently the center frequency and the frequency selectivity by providing a band pass filter current multiplier and divider circuit to the filter circuit. CONSTITUTION:A current IA flows through a resistor 12 by a current setting circuit 10 and a current IB flows through a resistor 13 by a current setting circuit 11. Then a current multiplier divider circuit 14 is provided in the filter circuit. Thus, a current I2 is formed by multiplication and division of the currents IA, IB and a constant current IC produced from a constant current circuit 15. Furthermore, the center frequency of and the frequency selectivity aQ of the band pass filter circuit depend on the currents IA, IB, IC, internal constants of variable gain amplifiers 4, 6, 7 and capacitors 3, 5. Thus, the center frequency of and the frequency selectivity aQ are compensated independently by the currents IA, IB. That is, they are compensated independently by resistors 12, 13.

Title: One-component type magnetic toner
Inventor: HOSHINO HIROYUKI
IPC: G03G9/083
Filed: 1981-01-08
Abstract: PURPOSE:To develop a latent image to form a high-quality print without defects lacking in image density near the middle part, by imparting anisotropy in electric conductivity, and magnetic dipole moment in that direction. CONSTITUTION:An electrically conductive paths 2 due to carbon black chains, polyacetylene, or the like are formed in the main component 1, such as polystylene or carnauba wax to impart anisotropy to electric conductivity, and magnetic particles 3 are caused to have magnetic dipole moment in the direction same as the direction of high conductivity of the toner to form toner particles 4. The toner 5 composed of these particles 4 is used for development. The toner 5 is conveyed by the magnetic force of a magnetic roller 6 onto an electrostatic latent image 9, and electric current flows through the toner chains formed with a magnetic field, because the conductivity direction is as same as the dipole moment direction. Accordingly, the electric field due to the image 9 induces charge on the toner 5, which is attracted toward the image 9, and attached to it, thus executing development.

Filed: 1988-01-05
Abstract: PURPOSE:To form a high-quality epitaxial film at a low temperature by a method wherein, after halogenated hydrogen gas has been mixed with a group III organic metal raw material gas, this mixed gas is decomposed in a reaction tube before it is introduced onto a substrate crystal and is then supplied onto the substrate. CONSTITUTION:A quartz susceptor 2 is installed inside a reaction container 1; a substrate crystal 3 is placed on it. The whole of the reaction container 1 is divided into three regions of a substrate-mounting region, a decomposition region at its upper stream part and an As supply region, at its upper stream part, where an As metal 7 is placed, and these three regions are heated independently. Individual gases are introduced into the reaction container 1 via a flow-rate controller 14 and a valve 15. A carrier gas of H2 flows through the As supply region; the substrate-mounting region and the decomposition region are heated individually. If necessary, the decomposition region is irradiated with a beam of a deuterium lamp 9. After that, HCl and TEG are supplied in order to grow GaAs. By this setup, the supply efficiency and crystallinity are not lowered due to precipitation and vapor nuclear growth during this process; a situation that a carbon impurity is taken into a growth film can be reduced.
